3 Claims. (Cl. I0821) This invention relates to sheet metal roofing, and has for its principal object the provision of a highly efficient, weatherproof, expansible sheet metal roofing construction which can be quickly, easily, rapidly, and economically installed. The invention is more particularly designed as an improvement over the roofing illustrated and described in applicants prior Patent No. 2,408,557, issued October 1, 1946.

Another object of the invention is to provide means for securely attaching sheet metal roofing strips to roof sheathing without interfering with the thermal expansion of the strips, and to provide highly eflicient means for finishing the roofing at the eaves, gable ends, and ridge of the roof.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and eificiency. These will become more apparent'from the following description.

In the following detailed description of the invention, reference is had to the accompanying drawing. which forms a part hereof; Like numerals refer to like parts in all views of the drawing and throughout. the description.

In the drawings:

Figs. 1 to 5, inclusive, are perspective-views of the five elements employed to form a complete roof with. the improved roofing;

Fig. dis a perspective view illustrating the method of applying the improved roofing;

Figs. 7, 8, and 9 are enlarged, fragmentary, detail sections, taken on the lines 7-7, 8-8, and 9-9, respectively, Fig. 6; and

Fig. 10 is a similar enlarged, detail. section looking downwardly on the line 10-10,. Fig. 9.

The five types of elements employed in the improved roof are: an elongated roofing strip 11, a batten strip 12,

a ridge member 13, a gable end member 14, and an attachment clip 15.

The roofing strips 11 are formed from sheet metal and are continuous in length with two upturned, parallel side flanges 16 extending along the side edges thereof. The upper extremity of the strip is provided with an upturned upper end flange 17, and the lower extremity is provided with a downturned lower end flange 18. A plurality of parallel, longitudinally extending stiffening ridges 19 are indented upwardly throughout the length of the strips 11. The ridges 19 serve a double purpose, first, they break the highlights of the conventional flat surfaces found in sheet metal roofing to produce an ornamental, roughened texture to the surface, and second, they act as stiffening members for the strips 11.

The batten strip 12 consists of an elongated strip of sheet metal bent to form a relatively sharp, concave ridge along the top. The two sides of the strip are bent downwardly, as shown at 20, and the lower edges of the sides are bent inwardly to form inwardly hooked edges 21. The upper extremities of the two sides 20 are turned outa straight, concaverid'ge along itsv top. The two side edges of the strip are bent back beneath themselves to form projecting edges 23'of double thickness, and are then extended downwardly to form two parallel sides 24.

The gable end member I4 is formed from an elongated strip of sheet metal folded longitudinally and upwardly on itself to form a double-thickness, vertical lower edge portion 25, thence folded outwardly to form a shelf portion 26 extending at right angles to the plane of the strip.

The attachment clip 15 is formed from relatively heavy metal, such as a die casting, to provide two side hooks 27 having upwardly extending, flange-receiving notches 28. The outer lower edges of the hooks 27 incline outwardly, as shown at 29', to form relatively wide, hook: engaging extremities. The clip is provided with a central nail hole 30.

The roof is preparedfor receiving the improved roofing by laying. tight sheathing boards 31 thereon, terminating at the gable ends in bargeboards 32 and at the eaves in eave boards 33. A wooden ridge cleat 34 is applied along each side of the roof ridge, as shown in Fig. 9.

The strips 11 are laid onthe sheathing boards 31 in parallel relation, extending from the hip or ridge to the eaves thereof; The upper end flanges 17 of the strips are nailed tothe cleats 34-, as indicated in broken line at 35, and the side flanges 16-are held in accurate, parallel relation by means of the attachment clips 15, the hooks 27 of which are fitted over the flanges 16 of the adjacent strips at spaced intervals. The clips 15' are nailed to the sheathing boards-31 by means-of suitable nails 36 placed in the nail openings 30.

It will be noted that there is no rigid attachment of the strips to the sheathing boards'31, so that the latter may freely contract andexpandlongitudinally under the influence of changes in temperature, the flanges 16 sliding into the notches 28 of the hooks 27 of the clips 15.

After the strips- 11 are in place, the ridge member 13" (of Fig. 3) is fit'ted'over the two ridge cleats 34 and over the flanges 17 of the strips and their nails 35.

' The batten strips 12' are now placed over the open joints between the adjacent strips" 1 1" and forced down' wardly over the clips 15. The sides 20 of'th'e batten strips 12 are formed in vertical, parallel planes. How-' ever, in forcing them over the clips, the sides 20' are forced outwardly by the inclined surfaces 29 until the hooked edges: 21 snap beneath the'widehook-engaging extremities of the hooks 27, as shown in Fig. 7, thus firmly locking the batten strips from upward movement.

The cars 22 at the upper ends of the batten strips 12 are nailed to the ridge cleats 34, through the upper end flanges 17 of the strips 11 and through the sides 24 of the ridge member 13, by means of suitable nails 37. The projecting edges 23 of the ridge member extend outwardly over the nails 37 and the cars 22 to conceal and protect the latter, and to prevent water from entering the upper ends of the batten strips.

The terminal strips 11 at the gable ends of the roof are spaced back from the bargeboards 32 so that the gable end members 14 may be nailed along the top of the bargeboards 32 or along the edge of the sheathing boards 31 to form a straight, finished edge therealong. The attachment clips 15 are then nailed in place through the shelf portions 26 of the members 14. One side hook of each clip engages the side flange of the terminal strip 11. The

other hook of each clip engages the upturned edge of the gable end member. The batten strips 12 are now placed over the clips, as shown in Fig. 7, to form a finished gable end on the roof.

The downwardly turned end flanges 18 of the strips 11 protrude downwardly beyond the eave boards 33 to provide an edge drip'for the roof. A conventional eave trough or gutter can be tacked in place along the cave boards 33, as indicated in broken line at 38, if desired.

It will be noted that the batten strips 12 can expand.

and contract thermally without loosening any of the roof structure, since they are anchored only at their upper extremities by the nails 37.

While a specific form of the improvementhas been described and illustrated herein, it is to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is:
